Her fourth and last marriage was infamous, known by contemporaries as the "diabolical marriage".[1] She married John Woodville, brother of Queen Elizabeth Woodville. He was 19 years old at the time of their marriage, while she was 65. Nonetheless, she survived him, as he was executed in 1469 after the Battle of Edgecote, on the orders of her nephew Richard Neville, 16th Earl of Warwick during a brief period of Lancastrian readeption. Whether or not she was forced into her final marriage against her will is unclear, but it added to the deep dislike of the Queen's family among the ruling class, which greatly weakened the Yorkist dynasty.
